DuPont™ Tychem® 9000 offers wide-ranging protection backed by extensive fabric permeation barrier testing. Tychem® 9000 fabric provides at least 30 minutes of protection against more than 280 chemical challenges, including chemical warfare agents. Tychem® 9000 offers tear, puncture and abrasion resistant fabrics for lasting protection. Tychem® 9000 garments are designed for enhanced comfort and ease of movement. High visibility yellow.

  • Encapsulated Level A garment design is our highest level of protection from liquid splash and vapor/gas exposures for both the wearer and respiratory equipment
  • Taped seams provide strong chemical resistance against heavy liquid splashes. A sewn seam is covered with a strip of compatible chemical-resistant material through heat sealing.
  • Expanded faceshield provides wide 220 degree viewing angle. EX faceshield is three-layer laminate composed of 40 mil PVC/5 mil Teflon® /20 mil PVC
  • Rear entry design keeps closure away from direct contact with frontal chemical exposure and provides ability to change air bottle on SCBA without removing the entire garment
  • Vapor tight zipper. Extra long to increase garment opening and aid donning and doffing
  • Storm flap covers zipper which can be secured by the wearer with rugged hook and loop material to prevent intrusion at zipper
  • Attached internal gloves composed of five layer laminate film for a broad range of chemical protection
  • Butyl gloves provide mechanical and physical durability to help protect inner gloves
  • Integrated socks composed of garment material
  • Attached flaps are designed to cover boot tops to help reduce potential for liquid intrusion
  • Two exhaust valves release higher pressure inside encapsulating garments while simultaneously helping to prevent inward leakage of external vapors or particles into the garment. One-way valves are positive pressure and open on demand. Valves include splash covers made of barrier material to help prevent liquid intrusion. Valves are located on left back of head and right lower back. (146)
  • Each suit has a unique serial number and is fully tested at time of manufacture including positive air pressure integrity testing per ASTM F1052.
  • Pass-thrus are optional and can be installed upon request when ordering. Some suits are available with optional pass-thrus to accommodate the following SCBA manufacturers: Scott, Interspiro, MSA, Draeger, Survivair®. Please call Customer Service 1-800-931-3456 for additional information. (3377)
